Full House Renovations

Whole-home transformations for houses and flats

A full house renovation London homeowners can live with for years is as much about sequence and coordination as it is about finish. We take on whole-home and flat renovation projects across the capital, including period properties where original features deserve to be kept and worked around.

Every room is planned together so that flooring, joinery, lighting and decoration follow one consistent standard, and the programme is organised to keep disruption to a minimum.

Kitchen Renovations

Kitchens planned for the way you cook, gather and live

A kitchen renovation in London often has to work hard in a limited footprint. We begin with the layout: where you prepare, where you store, how the room connects to the garden or the dining space, and where natural light falls through the day.

From there we help you settle on cabinetry, worktops, lighting and finishes that are practical to live with and pleasing to look at, then coordinate the agreed installation work from start to finish.

Bathroom and En-suite Renovations

Bathrooms that are calm, practical and beautifully finished

Whether it is a family bathroom, a compact en-suite or a separate shower room, a bathroom renovation needs careful planning of drainage, ventilation, storage and lighting before the finishes are chosen.

We work through the layout with you, then coordinate the plumbing, electrical, tiling and joinery so that every element arrives in the right order and the finished room is comfortable to use every day.

Alterations

Rework the layout and the whole house starts to make sense

Many London homes were laid out for a different way of living. Opening up a kitchen to the dining room, dividing a large room to create a study, or improving the connection between hallway, living space and garden can change how a home feels without adding a single square metre.

We plan each alteration around the existing structure, bring in the appropriate specialists where an assessment or approval is required, and carry out the work with the same care we give to finishes.

Loft and Basement Conversions

Underused space, brought into the home

A loft conversion or basement conversion can add a bedroom, a study or a quiet living room where there was once storage or empty space. Suitability depends on the property, which is why every conversion begins with a project-specific assessment.

The Project Journey

A clear path from first conversation to handover

This is how we propose to work with you. Each stage is agreed before the next begins, so you always know where the project stands.

01

Initial enquiry

Call us or send a short description of your project through the website, including your postcode and the rooms involved.

02

Discuss your requirements

We talk through how you use your home, what you would like to change and the finishes you have in mind.

03

Assess the property and scope

We visit the property, look at the existing layout and condition, and confirm what the work would involve.

04

Agree the proposal and programme

You receive a written proposal setting out the scope, and we agree a programme that suits you before anything begins.

05

Construction and coordination

Our tradespeople carry out the agreed work while we coordinate the sequence, deliveries and any specialists required.

06

Final review and handover

We walk through the finished rooms with you, attend to any snagging and hand over your home.

Craftsmanship and Materials

The quality is in the details you touch every day

A renovation is judged in the small things: the weight of a drawer, the line where worktop meets wall, the way a door sits in its frame. Our tradespeople are chosen for exactly this kind of attention.

Joinery

Cabinetry, wardrobes, panelling and built-in storage made to fit the room rather than the other way round.

Materials

Stone, timber, tile and brassware chosen for how they wear as well as how they look.

Finishes

Careful preparation, clean lines and consistent finishing across every room in the programme.

Coordination

Trades sequenced so that each finish is protected while the next is installed.

A Home Shaped Around You

Your requirements set the brief. We take care of the rest.

No two households use a home in the same way, so we do not work from a standard specification. We listen to how you live, what frustrates you about the current layout and the finishes you are drawn to, and we plan the project around those answers.

Throughout the work you have one point of contact who keeps you informed, raises decisions in good time and makes sure the details you care about are carried through to completion. The result is a home that feels personal rather than generic.

Frequently Asked Questions

Questions we are often asked

We carry out full house and flat renovations, kitchen and bathroom renovations, internal alterations such as opening up or dividing rooms, and loft and basement conversions. Smaller projects that form part of a wider programme, such as a new en-suite within a loft conversion, are included in the same scope.

Yes. Flat renovation London projects often involve lease conditions, shared services and access arrangements, so we discuss these with you at the outset and plan the programme around them.

Tell us about the room, its current layout and what you would like to change. We arrange a visit to assess the space and the existing services, then prepare a proposal covering the agreed scope of installation work and finishes.

A short description of the project, your postcode and property type are enough to begin. Photographs, measurements, drawings or a list of finishes you like are helpful if you have them, but they can follow after the initial conversation.

After assessing the property we set out the proposed scope in writing. Once you are happy with it, we agree a programme with you before work begins, and any changes along the way are discussed and confirmed before they are carried out.

It depends on the extent of the work. Single-room projects can usually be carried out with you in residence, while a whole-home renovation may be easier to manage if you can stay elsewhere for part of the programme. We will give you an honest view once we have seen the property.

Suitability depends on factors such as roof height and structure, access, drainage and the condition of the building, and it can only be confirmed through a project-specific assessment. We will tell you plainly whether a conversion looks feasible and what would need to be checked.

We are based in SE19 and work with homeowners and flat owners across London. If you are outside our usual area, send your postcode and we will let you know whether we can help.
